What is the flow rate of water through 0.75 inch pipe at 40 psi?

The flow rate of water through a 0.75-inch pipe at 40 psi can be estimated using the Hazen-Williams equation or similar formulas, which consider factors like pipe diameter, pressure, and water temperature. For a 0.75-inch schedule 40 PVC pipe, the flow rate at 40 psi is typically around 10 to 15 gallons per minute (GPM). However, specific flow rates can vary based on factors such as pipe length, fittings, and the condition of the pipe. It's best to consult detailed hydraulic tables or conduct measurements for precise calculations.
